# Load lists
#
# Masters should be in slot [0].
#
# All servers for which replication lag matters should be in the load
# list, not commented out, because otherwise maintenance scripts such
# as compressOld.php won't wait for those servers when they lag.
#
# Conversely, all servers which are down or do not replicate should be
# removed, not set to load zero, because there are certain situations
# when load zero servers will be used, such as if the others are lagged.
# Servers which are down should be removed to avoid a timeout overhead
# per invocation.
#
# Additionally, if a server should not to be lagged (for example,
# an api node, or a recentchanges node, set the load to at least 1.
# This will make the node be taken into account on the wait for lag
# function (the master is not included, as by definition has lag 0).
